GENERAL SAFETY PRECAUTIONS Before using a new chain saw • Please read this manual carefully. • Check that the cutting equipment is correctly ﬁtted and adjusted. See instructions under the heading Assembly. • Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping.
GENERAL SAFETY PRECAUTIONS We will willingly be of service and provide you with advice as well as help you to use your chain saw both efﬁciently and safely. Attend a training course in chain saw usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available.
GENERAL SAFETY PRECAUTIONS • The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism. • The brake is applied when the front hand guard (B) is pushed forwards or when the right-hand brake trigger (E) is pushed up and forwards.
GENERAL SAFETY PRECAUTIONS be activated manually by the movement of your left hand. • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action.
GENERAL SAFETY PRECAUTIONS Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle. Vibration damping system Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.
To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.
GENERAL SAFETY PRECAUTIONS • Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links. • Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design. Chain •...
GENERAL SAFETY PRECAUTIONS data for information on the size of ﬁle and gauge that are recommended for the chain ﬁtted to your chain saw. • Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difﬁcult to sharpen correctly.
GENERAL SAFETY PRECAUTIONS • Loosen the bar nuts that hold the clutch cover/chain brake. Use the combination spanner. Then tighten the bar nuts by hand as tight as you can. • Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner.
GENERAL SAFETY PRECAUTIONS • Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary. If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.
Fitting the bar and chain WARNING! Always wear gloves, when working with the chain. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. Remove the bar nuts and remove the clutch cover (chain brake).
When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor).
Fueling WARNING! Taking the following precautions, will lessen the risk of ﬁre: Do not smoke and do not place any hot objects in the vicinity of fuel. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently.
Starting and stopping WARNING! Note the following before starting: The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting. Never start a chain saw unless the bar, chain and all covers are ﬁtted correctly.
throttle latch in order to avoid unnecessery wear on the clutch assembly. Note! Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is ready for use. WARNING! Long term inhalation of the engine’s exhaust fumes, chain oil mist and dust from sawdust can represent a health risk.
Before use: Check that the chain brake works correctly and is not damaged. Check that the rear right hand guard is not damaged. Check that the throttle lockout works correctly and is not damaged. Check that the stop switch works correctly and is not damaged.
cause you to lose control. Both situations can cause serious personal injury. Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards. Fit a guard to the bar before transporting the chain saw or carrying it for any distance.
user. If the saw chain is jamming, the saw may be pushed back at you. Unless the user resists this pushing force there is a risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree, which can lead to a kickback.
Cut difﬁcult branches piece by piece. Cutting WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.
Make sure that no-one else is in this ”risk zone” before or during felling. Felling direction The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely.
Directional cuts To make the directional cut you begin with the top cut. Aim using to the saw’s felling direction mark (1) toward a goal further forward in the terrain, where you would like the tree to fall (2). Stand on the right-hand side of the tree, behind the saw, and cut with a pull stroke.
much greater risk that the kickback zone of the bar will come into contact with the tree. Freeing a tree that has fallen badly Freeing a ”trapped tree” It is very dangerous to remove a trapped tree and there is high accident risk.
Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object.

that the bar drops towards the stump as the chain saw rotates around the rear handle. When the bar hits the stump the brake should be applied. Checking the right-hand brake trigger Check that the right hand guard is not damaged and that there are no visible defects, such as cracks.
• Check that the throttle control and throttle lockout move freely and that the return springs work properly. • Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburetor idle adjustment.
Some mufﬂers are equipped with a special spark arrestor screen. If your machine has this type of mufﬂer, you should clean the screen at least once a week. This is best done with a wire brush. A blocked screen will cause the engine to overheat and may lead to serious damage.
A damaged air ﬁlter must always be replaced. A HUSQVARNA chain saw can be equipped with different types of air ﬁlters according to working conditions, weather, season, etc. Contact your dealer for advice.
Lubricating the bar tip sprocket Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. Needle bearing lubrication The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week).
”Air Injection” centrifugal cleaning Centrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed out by the cooling fan. IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained.
Maintenance schedule The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section. Daily maintenance Clean the outside of the machine. Check that the components of the throttle control work safely.
